[0024] In the construction of a full-face hard rock tunnel boring machine (TBM) tunnel project, according to the excavation characteristics of the equipment, the access sections of most tunnels need to be pre-excavated and supported, and two parallel and symmetrical full-face hard rock tunnel boring machine (TBM) sliding tracks are installed at the lower part of the access sections to ensure the smooth entry and exit of the full-face hard rock tunnel boring machine (TBM). Usually, the access sections of the tunnel are about 200 m long. The TBM sliding tracks need to be accurately installed one by one manually to ensure uniform force on the bottom of the TBM and the concrete pedestal. However, when installing the sliding tracks one by one manually, the accuracy cannot be guaranteed and the installation efficiency is low.

[0025] In view of the above problems, the embodiment of the present application provides an auxiliary device for installing a sliding track, which can fix the sliding track on both sides of the bottom of the tunnel through a horizontal crossbeam and a fixing plate, and cooperate with a spirit level to adjust the position of the sliding track to ensure the symmetry of the sliding track with the tunnel central axis, ensure uniform force on the bottom of the full-face hard rock tunnel boring machine and the concrete pedestal, and solve the problems of low construction efficiency and large error in the installation of the sliding track.

[0026] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0027] Figure 1 is the front view schematic diagram of the auxiliary device for installing a sliding track shown in the embodiment of the present application.

[0028] See Figure 1 , an auxiliary device for installing a sliding track, comprising:

[0029] a horizontal crossbeam 1, a fixing plate 2, a spirit level 3 and a sliding track 4;

[0030] The fixing plate 2 is processed from a square steel plate into a square frame. A square steel plate with a thickness of 12 - 20 mm is selected. According to the size of the TBM slide rail 4 installed on site, a cutout capable of buckling the slide rail 4 is cut at one corner of the square frame. The bottom of the cutout matches the arc guide base surface of the slide rail 4. Since the length of the horizontal crossbeam 1 is customized according to the spacing of the slide rails 4, the displacement of the two side slide rails 4 is restricted by the fixing plate 2. And the width of the fixing plate 2 is greater than the width of the horizontal crossbeam 1, so that the slide rail installation auxiliary device can be stably installed in the tunnel.

[0031] The horizontal crossbeam 1 is made of a straight square steel pipe. The horizontal crossbeam 1 is slightly longer than the spacing between the two ends of the slide rail 4 to be installed. According to the spacing at both ends, the fixing plates 2 are symmetrically welded to the bottom of both ends of the horizontal crossbeam 1.

[0032] The spirit level 3 is adsorbed on the steel horizontal crossbeam 1 through the magnet at the bottom. Through the bubble in the spirit level 3, it is judged whether the slide rail installation auxiliary device is horizontal, ensuring the accurate position of the slide rail 4 to be installed.

[0033] When installing the slide rail 4, two slide rail installation auxiliary devices are used in combination. The slide rail installation auxiliary devices are respectively placed at both ends of the slide rail 4. The spirit level 3 is placed on the horizontal crossbeam 1 and connected to the horizontal crossbeam 1 through magnetism. The construction workers judge whether the two side slide rails 3 to be installed are symmetric along the axis according to the horizontal bubble on the spirit level 3, and through manual fine-tuning, the slide rail 4 is installed and fixed in a flush and accurate manner.

[0034] The embodiments of the present application have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technologies in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein.
